# SudachiDict-full — Sudachi Dictionary for SudachiPy - Full Edition

License: permissive · Maintenance: active · Downloads: 742.1K/mo

## What it is and what it does

SudachiDict-full is a dictionary resource package for Japanese natural language processing, specifically designed to work with SudachiPy. It is one of three dictionary editions (small, core, full) and provides the most comprehensive morphological lexicon for tokenizing and analyzing Japanese text. The package manages dictionary resources as a Python package, automatically downloading the dictionary data during installation rather than bundling it directly.

The full edition is the largest and most complete option, suitable for applications requiring broad vocabulary coverage. It integrates with SudachiPy v0.5.2 and later, where you can specify the dictionary directly from the command line or program. Installation involves downloading a large archive, so it has high install friction but provides the most extensive Japanese morphological analysis capabilities.

Use it for:

- Building Japanese text search or indexing systems that require accurate morphological analysis
- Processing Japanese documents for NLP tasks like named entity recognition or dependency parsing
- Running production Japanese language processing pipelines where vocabulary breadth matters
- Developing Japanese chatbots or conversational AI that needs comprehensive tokenization

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides the full-edition Sudachi dictionary resource for Japanese morphological analysis with SudachiPy, downloaded and installed as a Python package.

Yes, if you are building Japanese NLP applications with SudachiPy and need comprehensive vocabulary coverage. The full edition is the right choice when broad morphological analysis is required. Be prepared for high install friction due to the large dictionary download. No known security vulnerabilities and active maintenance make it safe to use.

## Install

pip install sudachidict-full
uv add sudachidict-full
poetry add sudachidict-full

## Installing SudachiDict-full

Before you install: High install friction: the package downloads a large dictionary file (sudachidict_full-20260723.tar.gz) during setup. Active maintenance with recent releases; last commit 2026-07-24. Requires SudachiPy as a runtime dependency.

License in practice: Licensed under Apache-2.0 (permissive), allowing commercial and private use with minimal restrictions.

Quickstart:

pip install sudachidict_full

from sudachipy.tokenizer import Tokenizer
from sudachipy.dictionary import Dictionary

tokenizer = Tokenizer()
tokens = tokenizer.tokenize('テキスト')

Requires SudachiPy to be installed and functional; dictionary file is downloaded during installation, requiring network access and disk space.

Verify before relying:

- Exact disk space required for the full dictionary after installation
- Whether Python version constraints exist (requires_python is unspecified)
- Performance characteristics or coverage metrics for the full edition vs. core/small editions
